When you are hot and perspiring or working in tight quarters, the last thing you need are fogged safety or prescription glasses. And if a few drops of perspiration dance across the lens, well, that`s not good either. This handy lens cleaning system employs an anti-static, anti-fogging formula in a cleaning tissue to safely remove dirt, debris, and spots from glass and plastic lenses as well as a buffing cloth to dry the lenses. Each two-pack includes separately wrapped applicators and buffing cloths. Sold in 25 count packages.
